The particular metals named in describing this plate are merely forpurposes of illustration, as other suitable materials might be employedwhich, when completed into a plate as described, would result in a rigidconstruction providing a very eliicient p ate of low internal resistancefor alkaline batteries.

'What I claim as new and desire to secure by Letters Patent of theUnited States:

1. An active element for alkaline battery plates comprising a member.composed of separate cylindrical layers of active material and ofmetallic wire gauze arranged alternatel rw 2. As an article ofmanufacture, a cylindrical member composed of a metallic wire andalternate layers of a compound of the same metal and gauze of the samemetal.

3, Abattery plate comprising a retaining frame and active elements heldtherein, said elements consisting of rods composed oi concentric layersof active material, each layer being surrounded. by an envelop of wirewire and coating of nickel compounds thereon and an inclosing envelop ofnickel wire'gauze.

5. An active element for positive plates for alkaline batteriescomprising a nickel wire and alternate layers of a nickel compound, andmetallic nickel gauze thereon.

6. The method of forming an active element for alkaline battery plateswhich consists in coating a metallic core with a plastic layer ofmetallic compounds, drying the same, forming thereon a metallic gauze,coating with a plastic layer of the metallic salts, and forming thereonan additional wire mesh.

7. The method of forming an active element for alkaline batteryplateswhich consists in passing a metallic wire and a metallic salt in plasticstate through suitable dies, drying and annealing the same, and inclos-.ing the same in a wire gauze.

In witness whereof, I have hereunto subscribed my name in the presenceof two witnesses.
